DESCRIPTION
A/C COMPRESSOR
NOTE: Denso 10S17 A/C compressor shown. Visteon HS-18 compressor similar.
The A/C system on vehicles equipped with the 2.8L diesel engine use a Denso 10S17 ten cylinder, double-acting swash plate-type A/C compressor (1). This A/C compressor has a fixed displacement of 170 cubic centimeters (10.374 cubic inches).
The A/C system on models equipped with the 3.7L engine use a Visteon HS-18 A/C compressor. This A/C compressor is a 10 cylinder reciprocating swash plate-type compressor with a fixed displacement of 180 cubic centimeters (10.9 cubic inches).
Both A/C compressors have the suction and discharge ports (2) located on the compressor cylinder head (3) at the rear of the compressor and have a label identifying the use of R-134a refrigerant.
HIGH PRESSURE RELIEF VALVE
A high pressure relief valve is located on the A/C compressor. This mechanical valve is designed to vent refrigerant from the A/C system to protect against damage to the A/C compressor and other A/C system components, caused by condenser air flow restriction or an overcharge of refrigerant.
